U.S. Rep Steve King, R-Iowa, is back in hot water Sunday after tweeting support for far-right Dutch politician Geert Wilders, implying that “our civilization” can’t be restored with “somebody else’s babies,” referring to Muslims.

King quoted a tweet in which a cartoonist depicted Wilders using his finger to plug a wall with the words “Western Civilization" written on it. In the background, protesters hold signs saying, “Infidels, know your limits” and “Freedom of speech go to hell.” The tweet reads, “Hundreds of Islamists shouting 'Allahu Akbar' in Rotterdam, the Netherlands. Wilders is right for over 10 years. #turkijerel.”

A firestorm of criticism ensued with Twitter users citing the Republican Iowa congressman as a “bigot,” a “maniac” and an “embarrassment.”

Former President Bill Clinton’s daughter, Chelsea, reprimanded King for his comments, tweeting: “Clearly the Congressman does not view all our children as, well, all our children. Particularly ironic & painful on Purim.”

It’s not the first time King has gained notoriety for his controversial statements.

During the 2016 presidential election campaign, King, who supported President Donald Trump, said during a panel discussion on MSNBC that white people contributed more to civilization than any other “subgroup.”

In the summer, King came under fire for displaying a Confederate flag on his office desk, even though Iowa was a Union state during the Civil War.

In 2013, he claimed for every immigrant who is in the United States illegally and becomes valedictorian, there are “another 100 out there that – they weigh 130 pounds, and they’ve got the calves the size of cantaloupes because they’re hauling 75 pounds of marijuana across the desert.”
